Description

Technical Field

[0001] The invention relates to the technical field of insulator production equipment, in particular to insulator vulcanization molding equipment. Background Art

[0002] During the production of insulators, a hot press is required to wrap the glue around the outside of the core rod and perform vulcanization molding. In actual operation, the bottom layer of glue is manually laid on the surface of the lower mold, and then the core rods are manually placed one by one. During the placement process, the spacing must be uniform and compared with the mold cavity. Then the upper layer of glue is laid, and the mold is closed after completion. After vulcanization molding, the workpiece is manually taken out of the mold; the overall efficiency is low, and high temperature is required during the vulcanization process. During the mold opening process, both the upper and lower molds have high residual temperatures. There is a greater risk of burns during manual operation;

[0003] At the same time, the existing insulator core rods and terminal connection positions are combined by crimping, that is, the core rod is inserted into the cavity of the terminal, and radial pressure is applied to the outside of the terminal to combine the two. This causes the outside of the terminal to be non-absolutely circular, and the cross-section is runway-shaped. During the clamping process of the upper and lower molds, the mold cavities corresponding to the terminal positions are mostly circular in cross-section. This causes the thickness of the glue wrap at the pressed position of the terminal to be different, so that the insulator has different thermal deformation when used in an environment with a large temperature difference outdoors, resulting in cracks, shortening the service life, and affecting the use effect. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide an insulator vulcanization molding equipment, which adopts an automatic loading and unloading design to realize automatic laying of clay, automatic arrangement and automatic unloading of core rods, without the need for manual access to the mold, thereby improving efficiency and reducing the risk of burns. At the same time, through the positioning design of the core rod, the thickness of the external wrapping of the insulator is ensured to be consistent, avoiding cracks caused by uneven deformation, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an insulator vulcanization molding equipment, comprising a cement feeding part, a hot pressing forming part and a loading and unloading transmission part;

[0006] The hot pressing forming part includes an upper mold, a lower mold and a power mechanism for driving the two to separate the molds, and a heating mechanism is integrated in the upper mold and the lower mold;

[0007] The loading and unloading transmission part includes two groups of support brackets distributed on both sides of the hot pressing forming part, and the support brackets can slide horizontally and longitudinally, and can be lifted and lowered in the vertical direction;

[0008] The glue feeding part is arranged at the upper side of the upstream end of the hot pressing forming part, and includes a shaping roller that rolls oppositely and is used for feeding the glue, and a feeding telescopic rod that is arranged at the downstream side and is telescopic along the feeding direction of the glue; the free end of the feeding telescopic rod is vertically provided with an optical axis; it also includes a glue fixing block that can fix the front end of the glue to the upstream end of the lower mold, and a power mechanism that drives the glue fixing block to open and close;

[0009] When the feeding telescopic rod is at the minimum stroke, the cement passes over the shaping roller and the optical axis and can fall freely into the fixed area between the cement fixed pressing block and the lower mold;

[0013] The active baffle is provided with a piston cylinder connected to a power source and capable of moving laterally, and the passive baffle is provided with a floating plate installed by an elastic member and capable of moving laterally, and the piston cylinder and the floating plate correspond to two ends of the workpiece in the mold cavity one by one;

[0014] The outer end surfaces of the piston cylinder and the floating plate are both provided with concave spherical bowl surfaces or conical holes.

[0015] As a preferred technical solution of the present invention, the loading and unloading transmission part also includes a side slider, and the side slider is relatively slidably installed with the lower mold extending horizontally and longitudinally, and a lifting telescopic rod is vertically arranged between the supporting frame and the side slider.

[0016] As a preferred technical solution of the present invention, the front half of the support bracket is provided with a clamp for fixing the end of the insulator, and the rear half is provided with an arc groove for supporting the insulator.

[0018] As a preferred technical solution of the present invention, the outer rotating sleeve of the optical axis is provided with a sleeve.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: the insulator vulcanization molding equipment adopts a support frame to cycle loading and unloading, effectively shortening the loading and unloading process time, reducing the temperature drop of the upper mold and the lower mold during the process, reducing heat loss, and reducing the overall energy consumption of the equipment. At the same time, the operator is kept away from the mold to effectively avoid being burned;

[0025] At the same time, the core rod is fixed on the support frame, which can effectively ensure the stability of the angle of the core rod during the vulcanization process, that is, the pressing angle between the core rod and the terminal is consistent with the elliptical cross-section angle of the end of the mold cavity, thereby ensuring the consistency of the thickness of the outer wrapping layer of the insulator terminal, thereby avoiding the crack problem caused by inconsistent temperature deformation;

[0026] In addition, a cement feeding unit is used for V-shaped cement laying, and during the laying process, the support frame cooperates to arrange the core rod, which further shortens the working time required for loading and improves efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-Figure 9 , the present invention provides a technical solution: an insulator vulcanization molding equipment, including a cement feeding part 1, a hot pressing forming part 2 and a loading and unloading transmission part 4;

[0042] The hot pressing forming part 2 includes an upper mold 201, a lower mold 202 and a power mechanism for driving the two to separate the films. A heating mechanism is integrated in both the upper mold 201 and the lower mold 202;

[0043] The loading and unloading transmission part 4 includes two groups of support brackets 401 distributed on both sides of the hot pressing forming part 2. The support brackets 401 can slide horizontally and longitudinally, and can be lifted and lowered in the vertical direction;

[0044] The glue feeding part 1 is arranged at the upper side of the upstream end of the hot pressing forming part 2, and includes a shaping roller 103 that rolls oppositely and is used for feeding the glue, and a feeding telescopic rod 101 that is arranged at the downstream side and telescopic along the feeding direction of the glue; an optical axis 104 is vertically arranged at the free end of the feeding telescopic rod 101; it also includes a glue fixing block 404 that can fix the front end of the glue to the upstream end of the lower mold 202, and a power mechanism that drives the glue fixing block 404 to open and close;

[0045] When the feeding telescopic rod 101 is at the minimum stroke, the clay can freely fall into the fixed area between the clay fixed pressing block 404 and the lower mold 202 after passing over the shaping roller 103 and the optical axis 104;

[0046] When the upper mold 201 and the lower mold 202 are in a separated state, the optical axis 104 can be driven by the feeding telescopic rod 101 to cross the middle area between the upper mold 201 and the lower mold 202 .

[0047] During the design, the feeding telescopic rod 101 is arranged at an angle so that when the feeding telescopic rod 101 reaches the maximum stroke, the optical axis 104 crosses the gap between the upper mold 201 and the lower mold 202, and the horizontal height of the optical axis 104 is flush with the upper surface of the lower mold 202, or slightly lower than the upper surface of the lower mold 202, so that the lower layer of clay can fit more closely to the surface of the lower mold 202, and the upper layer of clay is in an oblique tension state under the joint tension of the optical axis 104 and the shaping roller 103. At this time, the downstream ends of the upper and lower layers of clay are connected, and there is a large gap between the two, which is convenient for the support frame 401 to place the core rod, and the clay will not interfere with the placement of the core rod.

[0048] See also Figure 8 After the upper mold 201 and the lower mold 202 are closed, a plurality of groups of mold cavities are provided inside to independently accommodate workpieces, and the large and small umbrella-piece mold cavities of two adjacent groups of mold cavities are arranged in a staggered manner; the cross section of the end of the mold cavity corresponding to the insulator terminal is an ellipse;

[0049] When designing the mold, the two insulators are staggered so that the large umbrella pieces and the small umbrella pieces of the two adjacent insulators are in the same plane. That is, when the upper mold 201 and the lower mold 202 are closed, the pressure-flowing clay mostly flows longitudinally, reducing the lateral flow of the clay, so that the clay can fill the mold cavity more quickly, and ensure the uniformity of filling at each position in the mold cavity, thereby reducing the waste of clay.

[0050] See also Figure 5 , further comprising a core rod arranging part 3, an active baffle 301, a passive baffle 302 and a driving telescopic rod 303 for driving the two to move relative to each other in the lateral direction distributed on both sides of the hot pressing forming part 2; the horizontal mid-surfaces of the active baffle 301 and the passive baffle 302 are both coplanar with the joint surface of the upper mold 201 and the lower mold 202;

[0051] The active baffle 301 is provided with a piston cylinder 3011 connected to a power source and capable of moving in the transverse direction, and the passive baffle 302 is provided with a floating plate 3021 installed through an elastic member 3022 and capable of moving in the transverse direction. The piston cylinder 3011 and the floating plate 3021 correspond to the two ends of the workpiece in the mold cavity one by one.

[0052] The outer end surfaces of the piston cylinder 3011 and the floating plate 3021 are both provided with concave spherical bowl surfaces or conical holes.

[0053] In order to match the arrangement of the insulators in the mold cavity, the active baffle 301 and the passive baffle 302 are used to align the two ends of the core rod first, and then the piston cylinder 3011 is actuated and the floating plate 3021 is used to float to achieve the axial stroke difference between the two adjacent groups of core rods, thereby meeting the final consistency requirements of the workpiece.

[0054] At the same time, the end faces of the piston cylinder 3011 and the floating plate 3021 both adopt a concave ball bowl structure or a conical hole structure. By setting the consistency of the axes of the two and the axis of the mold cavity in the mold, the relative position of the core rod and the axis of the mold cavity is fixed during the arrangement process, ensuring that the axis of the core rod can overlap with the axis of the mold cavity after the upper mold 201 and the lower mold 202 are closed, that is, the thickness of the clay wrapping on the outer circumference of the core rod is consistent, thereby reducing the crack problem caused by uneven temperature deformation.

[0055] See also Figure 7 The loading and unloading transmission part 4 also includes a side slider 403, which is horizontally extended and longitudinally slidably installed relative to the lower mold 202, and a lifting telescopic rod 402 is vertically arranged between the support frame 401 and the side slider 403;

[0056] By moving the lifting telescopic rod 402, the support frame 401 can move up and down to meet the needs of core rod arrangement and demoulding of the workpiece after vulcanization molding.

[0057] The front half of the support bracket 401 is provided with a clamp for fixing the end of the insulator, and the rear half is provided with an arc groove for supporting the insulator;

[0058] The front half of the support frame is a loading section 4012, which uses a clamp that matches the insulator terminal to ensure that the core rod will not rotate when it is arranged, thereby ensuring that the thickness of the glue wrapped around the core rod is uniform during the vulcanization process, and the rear half is a discharge section 4011, which uses an arc groove to facilitate the support of the end and increase the force-bearing area of ​​the insulator end during demoulding;

[0059] At the same time, during the design, in order to meet the flexibility of the production line and adapt to the production needs of insulators with different terminal styles, a detachable clamping plate 4013 is integrated in the support bracket 401, and the clamping plate 4013 is directly fixedly connected to the lifting telescopic rod 402. When the production product is changed, the original support bracket 401 is directly replaced with a support bracket 401 adapted to the new product, and the production line replacement can be completed quickly.

[0060] A base 204 is fixedly arranged below the lower mold 202, and horizontal longitudinal slide rails are arranged on both sides of the base 204, and a drive motor is built in; the side slider 403 is slidably installed with the slide rails, and has a rack meshing with the gear at the shaft end of the drive motor.

[0061] See also Figure 4 , the optical axis 104 is externally rotatably sleeved with a sleeve 105;

[0062] When laying the mastic, the direction of the mastic changes after it passes around the optical axis 104, and there is relative movement between the mastic and the optical axis 104. By adding the sleeve 105, the friction between the mastic and the optical axis 104 can be reduced, so that the mastic can pass around the optical axis 104 smoothly, reducing the stretching deformation of the mastic due to passing around the optical axis 104.

[0063] See also Figure 3 The hot pressing forming part 2 also includes a split mold telescopic rod 203 for driving the upper mold 201 to move; the split mold telescopic rod 203 includes a front telescopic rod 2032 and a rear telescopic rod 2031 vertically arranged at the upstream and downstream ends of the upper mold 201, and the lower ends of the front telescopic rod 2032 and the rear telescopic rod 2031 are both provided with a hard contact block and a limit sleeve 2034, and a spring 2035 is connected between the hard contact block and the limit sleeve 2034 along the axis, and the limit sleeve 2034 is fixedly connected to the upper mold 201;

[0064] When the mold is closed, the hard contact block directly contacts the upper mold 201 to guide the force. When the mold is opened, the hard contact block is separated from the upper mold 201, and the front telescopic rod 2032 and the rear telescopic rod 2031 guide the force to the upper mold 201 through the spring 2035.

[0065] The lower mold 202 is fixed, and the upper mold 201 is designed to be straight up and down, which has a simple structure and is easy to design and assemble;

[0066] At the same time, a flexible connection is adopted between the mold separation telescopic rod 203 and the upper mold 201. When the mold is closed, there is a rigid contact between them, which can quickly transmit force to ensure the mold closing pressure. When the mold is separated, the spring 2035 is used to transmit force, that is, when the mold is separated, the pulling force received by the upper mold 201 is not a sudden change force, but a linear growth force, and when the upper mold 201 is separated from the lower mold 202, the spring 2035 is subjected to a sudden change in force, and the upper mold 201 will have a rigid collision with the hard contact block, thereby causing the upper mold 201 to vibrate. If there is an insulator stuck to the upper mold 201, the vibration can cause the insulator to detach.

[0067] See also Figure 4 The hot pressing forming part 2 also includes a split mold telescopic rod 203 for driving the upper mold 201 to move; the split mold telescopic rod 203 includes a front telescopic rod 2032 and a rear telescopic rod 2031 vertically arranged at both ends of the upper mold 201; the front telescopic rod 2032 and the rear telescopic rod 2031 are both hinged to the upper mold 201; the top of the rear telescopic rod 2031 is vertically fixed, the middle section of the front telescopic rod 2032 is hinged with an oblique telescopic rod 2033, and the tops of the front telescopic rod 2032 and the oblique telescopic rod 2033 are both hinged and fixed;

[0068] When the molds are separated, the distance between the upper mold 201 and the lower mold 202 at the upstream end is larger than that at the downstream end;

[0069] The bottom of the mold-parting telescopic rod 203 is hinged, and an inclined telescopic rod 2033 is added, so that the upper mold 201 can be in an inclined state during mold parting, that is, the upstream opening is larger than the downstream opening, thereby facilitating the installation and arrangement of the clay feeding part 1, and facilitating the feeding telescopic rod 101 to carry the clay into between the upper mold 201 and the lower mold 202.

[0070] See also Fig. 9 The shaping roller 103 includes a lower roller 1032 with a smooth circumferential surface, and an upper roller 1031 with an annular groove on its circumferential surface;

[0071] During the production and transportation process, the putty is in the form of a continuous long strip with uniform thickness, which is transmitted on the guide plate 102. The shape of the insulator is a columnar body with large and small umbrella pieces arranged at intervals. Therefore, the amount of putty required to be wrapped at different positions is different. After the mold is closed, the high temperature of the mold itself will cause the putty to harden and its fluidity will decrease. Therefore, an upper roller 1031 with annular grooves and a cylindrical lower roller 1032 are used to pre-shape the putty, so that the thickness of the putty at the umbrella piece position is increased, while the thickness of the putty at other positions is reduced, thereby reducing the flow of putty after the mold is closed and meeting the need for putty to wrap the core rod.

[0072] When using:

[0073] First, with the help of manual or other feeding mechanisms, several groups of core rods with terminals are arranged in the fixture of the front half of the support frame 401, and after the vulcanization of the previous group is completed, the mold separation telescopic rod 203 drives the upper mold 201 to move up and separate the molds;

[0074] At this time, the lifting telescopic rod 402 drives the support frame 401 to rise, demoulding the vulcanized insulator, and the feeding telescopic rod 101 retracts from the maximum stroke to the shortest stroke, and at the same time the shaping roller 103 rotates to drive the clay feeding, and the clay bypasses the optical axis 104 and freely hangs down to the area between the clay fixing pressing block 404 and the lower mold 202, and the pressing block drives the telescopic rod 405 to move, so that the clay fixing pressing block 404 fixes the clay end to the lower mold 202, and at this time, the support frame 401 and the feeding telescopic rod 101 perform longitudinal movements synchronously to realize the unloading of the vulcanized insulator, the laying of the clay and the arrangement of the core rod, and after the core rod arrangement is completed, the support frame 401 moves downward, and after the subsequent equipment unloads the insulator, the support frame 401 is reset;

[0075] Then, the active baffle 301 and the passive baffle 302 in the core rod arrangement part 3 move to the specified position under the action of the driving telescopic rod 303, and the distance between the two is consistent with the length of the insulator, so that the two ends of the core rod are aligned. Then, the interval piston cylinder 3011 is actuated to arrange the core rods in a staggered manner. After adjustment, the mold is closed, and after heating and stabilizing the pressure, the mold is opened;

[0076] During the vulcanization production process, by adjusting the clay formula, the adhesion of the clay to the mold after vulcanization can be effectively reduced, that is, when demolding, most of the insulators remain in the lower mold 202. In this case, after the mold is closed, the core rod arrangement part 3 is directly separated from the core rod to avoid interference with the subsequent movement of the support bracket 401.

[0077] If the adhesive sticking is serious, there is a problem that the insulator is still stuck to the upper mold 201 after the mold is opened. At this time, after the mold is closed, the core rod sorting part 3 does not separate. When the mold is opened, it plays a limiting role for the insulator, causing it to separate from the upper mold 201. Subsequently, under the action of the rising support frame 401, the insulator is driven to separate from the lower mold 202.

[0078] Repeat the above steps to produce the next round of insulators.

[0079] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
